New description:
I don't see any good reason why the version number of Sage is used when
creating pickles using `sage.structure.sage_object.picklejar`
{{{
def picklejar(obj, dir=None):
"""
Create pickled sobj of obj in dir, with name the absolute value of
the hash of the pickle of obj. This is used in conjunction with
sage.structure.sage_object.unpickle_all.
To use this to test the whole Sage library right now, set the
environment variable SAGE_PICKLE_JAR, which will make it so dumps
will by default call picklejar with the default dir. Once you do
that and doctest Sage, you'll find that the SAGE_ROOT/tmp/
contains a bunch of pickled objects along with corresponding txt
descriptions of them. Use the
sage.structure.sage_object.unpickle_all to see if they unpickle
later.
INPUTS:
- ``obj`` - a pickleable object
- ``dir`` - a string or None; if None defaults to
``SAGE_ROOT/tmp/pickle_jar-version``
}}}
